The RA will review Computerized Patient Record System (CPRS) to confirm enrollment at the Durham VA Medical Center (DVAMC) or Raleigh Community Based Outpatient Clinic (CBOC), identify participants' primary care provider and conduct a preliminary medical record review of the exclusion criteria listed above.
